[Feature request] Sourcemap report

[exodus4d]

Very nice tool! ❤️

It would be awesome if you could add support for JS sourcemaps as well. Like the "minified" report, we could check filepath.match(/\.map\./g files and add sizes to a new row (optional).

This would help to analyse the sourcemap build process. E.g. whether they are:

• inlined in the src *.js file

• inlined in the src *.js.map file

• reference to src *.js in *.js.map file e.g. build.js.map:

  {
    "version":3,
    "sources":["first.js", "second.js"],
    "names":[....],
    "mappings":".......",
    "file":"build.js",
    "sourceRoot":"../src"
  }
  

There are some other options as well. But I guess there are the mainly used options.
